pleasure of the visit to the wonderful cave, which they regard with
affection and pride, very cordial thanks are due to Capt. T.S. Powell,
former manager, his son, Mr. Will Powell, the first guide, and Mr. Fred
Prince, who has made the only official survey and map. It may be stated
here that the survey and map are far from complete, and many known
passages have never yet been entered.

Being the first visiting party of the season, certain disadvantages were
encountered in a great accumulation of wet clay and rubbish, washed in
by the rains since the previous summer; but the gate was opened with
considerable effort, and slowly and cautiously we descended the
slippery, clay-banked stairs to the immense mound of debris forty-five

The magnificence of that one chamber should give to Marble Cave a
world-wide fame even if there were nothing more beyond. The blue-gray
limestone walls have a greater charm than those of an open cañon, owing
to the fact that they sweep away from any given point in long, true
curves to form an elliptical chamber three hundred and fifty feet long
by one hundred and twenty-five feet wide, with the vault above showing
absolute perfection of arch, and measuring, by the survey, from its
lowest to its highest point, one hundred and ninety-five feet. These
measurements are said to be indisputably correct, and if so, the

architectural form, its acoustic properties having been tested, it is
found to be truly an auditorium. The curving walls and pure atmosphere
combine to aid the voice, and carry its softest tones with marvelous
distinctness to every portion of the immense inclosed space. As a
